DESK BOOK-BACK. I

Specification of Letters Patent.

Patented Jan. 11, 1910;.

Application filed April 25, 1907. Serial No. 370,266.

. To all whom it may'concem:

a number of books,

Be it known that I, WILLIAM B. UPDE- GRAFF, a citizen of the UnitedStates, residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in DeskBook-Racks, of which the following is a specification.

My invention relates 'to improvements in desk book racks.

The object of my lnvention is' to provide a rack of this character soconstructed and arranged'that it can be adjusted to hold any desirednumber of books in their upright position and upon the removal of abook, or it can be adjusted toproperly support the remaining bookswithout removing the same or injuring them in any way.

Another object of my invention is to provide a simple, cheap and moreeffective rack of this character. In the accompanying drawings: Figure 1is a perspective view of my improved rack; Fig. 2 is an enlarged endview, partly broken away; Fig. 3 is a vertical sectional view taken onthe line m -m of Fig. 2; Fig. 4 is a sectional-view, showing the tubeexpanded within the end plate; Fig. 5is a sectional view, showing a roddriven into the end plate and frictionally held; and Fig. 6 shows ascrew-threaded connection between the tube or rod and the .end plate.

'Referring now to the drawings, 1 and 2 represent the enlarged endplates, each of, which consists of an enlarged vertical and circularportion 3 connected to the horizontal base "A'by means of the arms 5,all of which are formed integral, and preferably made-6f a single-casting,'although the plates could be otherwise formed. As shown, theinner faces of'the circular portion 3, arms 5 and base 4 are perfectlysmooth and flush with each other, as will be hereinafter more fullydescribed. The outer faceof the circular portion is provided with anannular flange 6 which forms a depression 7, to which any ornamentaldesign may be cemented or otherwise secured. This arrangement isespecially designed to receive and hold the emblem of some college,whereby such emblem could be readily placed in the rack and the samefurnished to the students of the various colleges, with the emblem oftheir college therein, thus producing a simple and nove device.

The lower face of the horizontal base 4 is provided with a recess 8 inwhich is placed and prevent the base from scratching the same. Eachface, on its inner face and adjacent its ends, is provided with annularrecesses 10 and 11 which extend nearly through the base and havecommunicating therewith the openings 12 and 13 which are of a diam;-eter considerably less than that of the rethe rubber blocks 9 which restupon the desk I cesses,.thus formin the shoulders 14. The

tubes 15 are driven 1nto the recesses and abut against the shoulders 14,and by means of any suitable expanding tool inserted through theopenings 12' and 13 they are expanded and securely locked in the' bases.The open- .ing 10 and 11 of the plate 2 is larger than the opening inthe plate'l, so as to. receive tubes of different sizes and so that thetubes of plate 1 will telescope within the tube of late 2 and thus thetwo plates can be 'adusted close together or far apart according to thenumber of books to be held thereon. The friction-between the telescopingtubes holding them in their adjusted position.

The tubes are so spaced apart thatthey form a support for the books andthus evenly support the books and revent any tiltin of the same. Theoutsi e tubes are beveled at 16 to prevent injury to the edges of thebooks when adjusting the rack with books thereon. In some instances ithas been found preferable to use tubes in one section and rods 17 inanother, and, in such case, the base is simply provided with a recess 18and the rod 17 is driven therein and frictionally held as shown in Fig.5. As shown in Fig. 6, the recess 18 could be screw-threaded at 19 andthe rod screwed therein.

The tubes while described as being expanded within the recess in thebase could be readily 'frictionally held or screw-threaded, as describedin respect to the rod 17.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is: v 1. A desk book rack comprising endplates, having bases supporting the plates in a vertical position andthe inner faces of the plates and bases being flush, the inner face ofthe bases adjacent their outer ends having recesses, and tubes expandedwithin said recesses, and the tubes of one base telescoping the tubes ofthe other base, whereby the end plates are adjustably held and the tubesserving as a support for the books.

2. A desk book rack, comprising circular end plates supported by armsupon'horizontal bases, the inner faces of the plates, arms and basesbeing flush, the outer face of the plates having an annular flangeforming a central depression to which any desired ornamental plate maybe secured, the said bases having recesses in their lower faces, rubberblocks secured within said recesses, and horizontal tubes carried by thebases and telescoping each other, the outer tube having its inner facebeveled.

, 3. A desk book rack, comprising end plates supported by arms uponhorizontal bases,'the

inner faces of the plates, arms and bases being flush, the outer face ofthe plates having a flange forming a central depression in Which anydesired ornamental plate may be secured, the said bases having recessesin their inner faces adjacent the ends, and tubes secured with saidrecesses and telescoping each other.

4. A desk book rack, comprising end plates supported upon bases, thesaid bases having recesses in their inner faces and openings of adiameter less than the recess in co1n1nunication with the recesses fromthe other faces of the bases, tubes extending Within the recesses andexpanded through the openings, the tubes of one base telescoping withthe tubes of the other base, the outer tube having a beveled end. p

In testimony whereof I aflix my signature in presence of two witnesses.
